IM PROVED 'RAILWAY-CAR Specification forming part of Letters rPatent No. 45,316,V dated December 6, 1864. V

I'o all whom it may concern -Be it known that I, THOMAS Cns'rog, of hiladelphia, Pennsylvania, have invented an Improvement in Railway-Cars; and I do here- 'by declare the following to be a full, clear, and

exact description of the same, reference being hadto the accompanying drawings and to the letters of reference marked thereon.l

first, in dogsfso con- VMy 4invention consists,

to a rai Avay-car `iu strueted and so Y hung 'respect to the wheels that they will eliectively, .remove .objects from the tra'ck and prevent them'from' being acted on by the 'wheels secondly, in the combination ofthe said Vdogs with bars attached to the axle so that 'the dog's will always be maintained at the saine distance above the track thirdly, in such a combination 'of parts described hereinafter as will insure the eiective operation ofthe dogs.

In order to enable others skilled in' the art to make and use my invention, l will now proceed to describe its construction and opera tion.

y O n reference to the accompanying drawings, which form a part of this speciiieation. Figure l lis a side view ofv suicient of a railwayca'r to show my improvement; and F ig. 2, an end view, partly in section. A

Similar letters refer to similar parts vthroughout he several'views.

A represents the frameof the car,and B the axles, which turn in vsuitable boxes, a, adapted to vhangers C, the axles being' provided with D D. Between the situated a bar, c, the ends of which' projectbeyond the outer' edges of the wheels., andnear each end of each bar is secured an 'shaped plate, b,w hiehis attached to the axle box a, as best shown in Fig. 2.

Near each end of each bar c, 'an arm, D, is' hung loosely, the lower end of each arml being bent upward, so as to form a yoke, tothe inner arm of which is attached one end of a rod, E, 'the other end ofthey said rod being connected to the yoke on the opposite side of the car.

Within the yoke formed by the bent portion of each arm D a dog, F, or the form shown inthe drawings, is hung loosely, the said dog occupying a position over therail. directly in front ofthe wheel, the cuter arm of the dog being somewhatlonger and heavier than the Inner arm, for a purpose described hereinafter. So long as the car meet-s with no obstruction I .in-its forward'm'otion the arms D will hang peri pendicular tothe rails, and the outer ends of the dogs will bear lightly on and 'slide over the treads 0f the same, and, should even the smallest or lightest object lie upon the rail, the dog will push the 'saine When, howeverptheend of the dog engages lwith an object which is too large or heavy to be readily pushed from th'e rail, the end ofthe arm D will bermoved back toward the wheel,

so that the inner arm of the dog shall coinen contact with the periphery of the'sanle, and be thereby depressed," the other arm being con-V sequently raised-'so as to litt the object from the track and throw it to-.one side or lche other. Should the object, however, be so large as to bear upon the end of the dog after the latter is raised, the dog, by its con tnued press"` ure against the periphery of the wheel, will act as a brake, and, by suspending or intenrupting therevolution of the wheel, tend retard the further progress of the car,jthe` arm D preventing the objecten the do gtroml contact with the edge ofthe" weh eomingiu n As the bars c are attached to the '-"`-axle, boxes, it willbe apparent that the distance between the dogsand the rails willnot be aff fected in any mannerby 'the movements of the body of the car.v

When itis desired' to prevent the arm I) from being too readily Inoved toward the wheel,a spiral spring,v c`,1niay be' attached to the arm and to some j'stationary portion of the car, the said spring'` tending to maintain the arm in its perpendicular position.

I claim as'my invention and desire to secure by Letters Patentl. A dog, F, so constructed, and schung to Y wheel that it:

a railway-cnr inV respect to the will operate on obstructions on .therail as set forth. I

2. The combination of the-saiddog F with a bar attached to the axle boxes asset forth.

3.l The arm L, dog F, and r.barc, combined,

and arranged inrespect to a Vrailway-car substantially as specified. ,l f

ln testimony whereof I have signed my naine to this speeiiicatien in the 'presence' of two subscribing witnesses.
